Product Information

Full details

The Brompton Gear Cable Anchorage (Part #9011070) is an essential maintenance component designed specifically for owners of Brompton folding bikes equipped with Sturmey Archer internal hub gears. It provides a secure, precise connection point for your gear cable, ensuring reliable indexing and smooth shifting across 3-, 5-, and 6-speed configurations. While it is a critical part for drivetrain integrity, users should note that precise adjustment of the cable tension is required during installation to maintain optimal shifting performance.

FAQs

Is this part compatible with non-Sturmey Archer hubs?

No, this specific anchorage (9011070) is designed exclusively for Sturmey Archer hub gear systems.

Do I need special tools to install this?

You will need a standard set of hex keys or wrenches appropriate for the bolt type, as well as cable cutters if replacing the cable.

How often should I replace the cable anchorage?

It is not a part that needs scheduled replacement, but it should be changed if you notice signs of wear, deformation, or if the bolt threads are damaged.

Can I use this on a single-speed Brompton?

No, single-speed Bromptons do not use this gear cable anchorage as they lack an internal hub gear mechanism.

Troubleshooting

Gears are skipping or not engaging

Check the cable tension at the anchorage and adjust the barrel adjuster on the shifter until the indicator chain is correctly positioned.

Anchorage bolt keeps slipping

Ensure the cable is not frayed and the anchorage bolt is tightened firmly; if the threads are stripped, replace the anchorage unit.

Pros and Cons

Pros

  • Ensures accurate gear indexing for Sturmey Archer hubs
  • Direct OEM replacement for factory-installed parts
  • High-quality material designed for longevity under tension
  • Simplifies the cable replacement process for multi-speed hubs

Cons

  • Requires mechanical knowledge to install and calibrate correctly
  • Not compatible with derailleur-only gear systems
  • Minor adjustments may be needed after initial installation

Setup, Compatibility & Care

To install this anchorage, ensure your gear shifter is set to the lowest gear position to provide maximum cable slack. Carefully thread the gear cable through the anchorage and tighten the bolt once the cable is taut and properly seated in the hub gear mechanism.

Compatibility: This part is compatible with all Brompton bicycles using Sturmey Archer internal hub gears (3, 5, and 6-speed models).

Care: To extend the life of this component, keep the cable clean and lightly lubricated. Periodically check the bolt tightness to ensure that vibration during cycling has not caused it to loosen. If you notice signs of corrosion or fraying of the cable at the point of contact, replace the anchorage and cable simultaneously to ensure safety.
